Under the same condition, the cement mill output will be increased if the circulating load in the cement mill is increased. But the larger cycle load rate will make the powder efficiency decline, many qualified products cannot be selected out, back to the grinding cycle, limiting the increase in the cement mill output. This is a paradoxical state.
